Not sure.

I haven't done combined mdt/mgs for a while, so I can't recall if you
have to specify the mgs NIDs for the MDT when it is colocated with the
MGS, but I think the command should have been more like:
# mkfs.lustre --fsname ${FS_NAME} --mdt --mgs --failnode=${MGS_2}
--mgsnode=${MGS_1} --mgsnode=${MGS_2} /dev/md10
with the mkfs/first mount on MGS_1.
As I mentioned, you would not normally specify the mkfs/first-mount NIDs
as failover parameters, as they are added automatically by Lustre.
